Meanwhile Ballmer looks to pump shareholders up with a letter emphasizing Microsoft's success

When a more mature Steve Jobs came back to Apple, Inc. (AAPL), he revitalized the company he co-founded as a rebellious youth. Millions of iPods, iPhones, and iPhones later, Apple is the world's most valuable company in terms of market cap. Meanwhile, Apple's perennial rival Microsoft Corp. (MSFT) is struggle not for want of user, but for a faltering brand image. Some say that Bill Gates -- the man who founded Microsoft and drove it to its initial success -- should return.

Steve Jobs did a phenomenal piece of work. Apple, most people would have expected, were on their way going out of business. He had run Apple since it was a tiny company and then he came back in and made incredibly valuable. It’s a phenomenal business story and I thought Walter Isaacson did a good job catching that in the book. Steve and I were friends, competitors – we were a lot of different things. It was amazing what he did.

I’m now committed full time to my foundation work and I give about 15% of my time as Chairman of Microsoft. Microsoft is moving ahead with Windows 8 that combines the best of tablet with PC. This month the very first hardware based on that idea including Microsoft’s own Surface will ship. So there’s a lot of exciting stuff ahead in software and I didn’t retire from Microsoft because I thought things were getting boring. In fact a lot of best ideas- the vision of artificial intelligence and robots are still ahead but i did decide the philanthropic world was where my contribution would be more unique and so thats what I’ll work on full time for the rest of my life.

Some people will be disappointed that Mr. Gates is resisting a comeback.

II. Steve Ballmer: Microsoft is Strong

But Microsoft CEO Steve Ballmer is convinced no comeback is necessary. He insists that the image that Microsoft lacks creativity is badly out of date. In a letter to shareholders, he brags that 1.3 billion people worldwide use Windows and that there are 8 million active Windows app developers.

For fiscal year 2012, revenue grew to a record $73.7 billion. We also maintained strong cost discipline resulting in cash flow from operations of $31.6 billion, an increase of 17 percent from the prior year. In addition, we returned $10.7 billion to shareholders through stock buybacks and dividends.

In other words financially Microsoft shows little sign of being a "dying" brand as some opinion pieces have claims.

Windows 8 is a huge risk. But Steve Ballmer is convinced it will pay off, even as Bill Gates watches -- permanently -- from the sidelines.

Theres loads of reasons... the main ones being faster speed, lower memory usage, better security + built-in AV (that actually works very well i've found). Then theres features like Storage Spaces which i personally would get Win 8 for alone. The better multi-monitor support is also nice, if late. I also like the new File Explorer and the simple things like finally being able to pause file copying. It's also fixed issues i've had with old and not well known games, which would crash on start on Win 7.

Theres more desktop improvements in 8 than there was with 7 compared to Vista. For $40 i dont see any reason not to just upgrade. If you're on Win 7 it will keep all your settings and files.

Windows "Upgrades" have kept settings and files since the Win2K era. It is generally considered a mortal sin to actually "upgrade" any version of windows. You load it fresh and then migrate the data over afterwards. In place upgrades only serve to cause weird shit to happen down the line that there is no explanation to other than "must be something carried over from the previous OS".
